Description of Ti-45Nb Titanium Alloy Wire And Bar

(Titanium Alloy Grade 36/55Ti-45Nb Alloy)

Originally developed for application as an aerospace alloy because of its relative ease of formability, high strength, and ductility at temperatures up to 427°C (801°F), Ti-45Nb Titanium Alloy is an ideal candidate for rivets that secure aluminum aircraft panels, particularly in areas exposed to high engine exhaust temperatures.

This alloy has been used as welded flange components that secure high-energy physics RF linear accelerator cavities (made from high-purity niobium) and has been drawn into superconductivity wire. It is used as a medical device material for cochlear hearing implants and its low elastic modulus makes the material considered for a variety of medical and dental devices.


Ti-45Nb Titanium Alloy is easily fabricated into structures and components. Although it is considered a refractory metal, processing techniques are the same as those for other titanium alloys. Parts are typically welded using the GTAW process but require the addition of trailing and backing shields and due to its simple metallurgical structure, there is no requirement for post-weld heat treatment. Machining requires the use of solid fixture setups and high torque at low RPM ridge machine tools with sharp high rake cutters.

With an exceptionally small bend radius capability (down to a bend radius of 1t where t=sheet thickness) and low modulus of elasticity, Ti-45Nb Titanium Alloy is highly formable and yet still retains excellent tensile and elongation properties. It can also be cast into shapes with the same processes used to cast CP titanium.


Ti-45Nb Titanium Alloy readily accepts surface oxidation treatment to enhance its hardness and wear resistance.

“Mobilizing” is a common commercially available process to apply this type of surface treatment.


Ti-45Nb Titanium Alloy provides improved corrosion resistance along with higher strength compared to that of Ti-7, 12, 16, and 26 in many chemical environments. Ti-45Nb Titanium Alloy has also proven to be a great success in the autoclave processing of gold ore. For many years gas vents, oxygen lances, steam spargers, valves, and other pressure oxidation reactor components have been produced, put into service, and survived hot, concentrated sulfuric or hydrochloric acid. In addition, the metal has been shown to have higher ignition resistance when compared to CP Ti, thereby allowing further process optimization.


Another chemical processing application for Ti-45Nb Titanium Alloy is the oxygen-based, low-pressure, wet oxidation process (LoProx*) for the treatment of wastewater and sludge. Because of its corrosion and higher ignition resistance, this material is an ideal candidate for the 200°C (392°F), 20 bar pressure with an oxygen environment. The superior corrosion resistance of Ti-45Nb Titanium Alloy makes it well-suited for service in a variety of environments including most organic and mineral acids below 150°C (302°F). Because of its stable oxide film, Ti-45Nb Titanium Alloy has excellent resistance to oxidizing acids including mixtures of HNO3 and HCl; however, it is susceptible to attack from HF and other fluoride ions.
